Jute Processing in Rotor Spinning for Making Jute and Jute Blended Fine Yarn

Abstract

Jute is a natural bastfibre popularly known as the golden fibre. It has been used for thousands of years to made rope, twine and hessian. Recently jute has been considered as a technical fibre throughout the world for diversified uses, such as composite material, geo-textile, decorative fabric, fine fabric etc. A good quality yarn is essential for making desired fabrics/products. Selection of suitable spinning machine is most important for making a particular type of yarn. Spinning is the process where jute yarns are spun from finisher drawing sliver with the help of spinning machine. There are many type of spinning. Flyer and ring spinning are commonly used for jute fibre, however ring and rotor for cotton and manmade fibre. Rotor spinning is suitable for coarse and medium count cotton yarn. In this study jute and jute-acrylic blended yarns of 172 tex were produced by using rotor spinning and conventional apron draft flyer spinning machine. Characteristics of yarns produced by both systems were compared. This work reports how jute fibre can be used as raw material in short staple spinning process along with acrylic, polyester, cotton etc. fibre to make fine yarn for apparel fabrics. The present work is concerned with the investigation into physical properties such as tenacity, elongation at break, breaking work, breaking force, unevenness, thick, thin, neps, hairiness of jute blended rotor spun yarn. The process parameters such as blend ratio, twist, machine variables and yarn linear density were also studied and optimized for manufacturing of jute and jute blended yarn. The results show that rotor speed and twist have considerable influence on properties of yarn. From the mechanical/physical properties of yarn produces by using rotor spinning machine, it is clear that rotor spinning has a potential feasibility in use of jute yarn production.
